OJD shock drives biosecurity improvements at Bordertown

May 27, 2014

A surprise positive for ovine Johne’s disease (OJD) jolted Bordertown farmer and 2013 Animal Biosecurity Farmer of the Year finalist Richard Halliday to reassess every aspect of his farm management and implement major changes to his biosecurity system.

A routine pooled faecal culture (PFC) test conducted in July 2012 came back with the out-of-the-blue result, with follow up polymerase chain reaction (PCR) tests confirming the OJD infection in a single animal.

The infection within Mr Halliday’s Callowie Poll Merino stud flock set off a costly chain of events to rid the property of the disease, but which have ultimately led to a more thorough biosecurity system to prevent future disease incursions.
